After 15 months of marriage, Amber Heard and Johnny Depp have decided to end their relationship. The couple has not revealed what led to their decision to call it quits, but a new report claims Depp’s family may have driven a wedge between him and the actress.

Multiple sources told TMZ that there was a “full-blown feud” between Depp’s family and his wife. Supposedly, the actor’s mother Betty Sue Palmer, his sisters and two kids, Lily-Rose and Jack, “hated” Heard. According to the outlet, they all believed Heard was using Depp for his fame and thought she treated him “like crap.” Palmer was also upset that she supposedly only got to see Depp, 52, one time since he and Heard married in February 2015.

Over the course of their marriage, Heard and Palmer had two different sit-downs to try and work out their issues, but things between them never got resolved. During one of their meetings, TMZ reported that it ended with Palmer calling Heard a “terrible person.” The sources claim the tension only got worse when Palmer moved into Depp and Heard’s Los Angeles home. Palmer died last week, just a few days before Heard filed for divorce.

According to E! News, the 30-year-old actress cited the reason for their split as “irreconcilable differences.” A source also said the pair didn’t have a prenuptial agreement, and Heard is asking for spousal support. Although TMZ reported that Heard wasn’t getting along with Depp’s two children, the “Magic Mike XXL” star did an interview for Marie Claire in November in which she said being a stepmother to Lily-Rose and Jack was the “greatest, most surprising gift.” She added, “I feel new flavors that I didn’t know existed. New colors that I didn’t know existed have been added to my life. I’m so happy.”
